Abstract
The utility model relates to a lifting machine, in particular to a falling-proof lifting machine. The lifting machine comprises a bracket, a rear arm, a front arm, a hinge shaft, a winding roll, a steel wire rope, a fixed pulley and a hook; the bracket is provided with the rear arm fixedly connected with the front arm through the hinge shaft; the winding roll and the fixed pulley are arranged on the front arm; the steel wire rope is placed on the winding roll and the fixed pulley; the hook is arranged at the top end of the steel wire rope; a fixing rack is arranged on the front arm hinged to a fixing ring; the fixing ring is fixedly connected to the hook; the steel wire rope is placed in the fixing ring; the fixing ring and the hook are fixedly connected with each other through a pull rope; clamping teeth are arranged on the inner layer of the fixing ring. The lifting machine can timely prevent the hook from falling off before the steel wire rope breaks, so as to avoid property loss and personnel safety problems due to the falling of articles.
Description
Technical field
The utility model relates to a kind of lifting machine, especially fall arrest type lifting machine.
Background technology
A kind of handbarrow that on lifting machine, building ground or manufacturing industry are often used, it can move heavy weight object, thereby can increase work efficiency greatly, but because existing lifting machine is in the time lifting by crane, can make hanging object drop thereby may there is fracture because of steel rope, thereby cause that article damage and safety misadventure.
Utility model content
May be because of the rope deficiency that article are dropped that ruptures in order to overcome existing lifting machine, the utility model provides fall arrest type lifting machine.
The utility model solves the technical scheme that its technical matters adopts: fall arrest type lifting machine, comprise support, postbrachium, forearm, hinge axis, winding roll, steel rope, fixed pulley and hook, support is provided with postbrachium, postbrachium is fixedly connected with forearm by hinge axis, forearm is provided with winding roll and fixed pulley, steel rope is placed on winding roll and fixed pulley, steel rope top is provided with hook, forearm is provided with fixed mount, fixed mount and set collar are hinged, set collar is fixedly connected with hook, and steel rope is placed in set collar.
According to another embodiment of the present utility model, further comprise between set collar and hook and being fixedly connected with by stay cord.
According to another embodiment of the present utility model, further comprise that set collar internal layer is provided with latch.
The beneficial effects of the utility model are, this lifting machine can be prevented hook in time and drop in wire cable rupture, thereby avoid occurring article drop caused property damage and personal safety problem.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. supports in figure, 2. postbrachium, 3. forearm, 4. hinge axis, 5. winding roll, 6. steel rope, 7. fixed pulley, 8. hook, 9. fixed mount, 10. set collar, 11. stay cords, 12. latches.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, fall arrest type lifting machine, comprise support 1, postbrachium 2, forearm 3, hinge axis 4, winding roll 5, steel rope 6, fixed pulley 7 and hook 8, support 1 is provided with postbrachium 2, postbrachium 2 is fixedly connected with forearm 3 by hinge axis 4, forearm 3 is provided with winding roll 5 and fixed pulley 7, steel rope 6 is placed on winding roll 5 and fixed pulley 7, steel rope 6 tops are provided with hook 8, forearm 3 is provided with fixed mount 9, fixed mount 9 is hinged with set collar 10, set collar 10 is fixedly connected with hook 8, steel rope 6 is placed in set collar 10, between set collar 10 and hook 8, be fixedly connected with by stay cord 11, set collar 10 internal layers are provided with latch 12.
In the time of crane normal operation, set collar 10 keeps vertical with forearm 3, and now steel rope 6 transmission between fixed pulley 7 and winding roll 5 does not hinder, and stay cord 11 now is not given any pulling force of set collar 10.After steel rope 6 fractures, when linking up with 8 related goods and down falling together, stay cord 11 can be to 10 1 downward pulling force of set collar, the set collar 10 being now hinged with fixed mount 9 can rotate, set collar 10 can compress steel rope 6, thereby stop steel rope 6 further to glide, and latch 12 on set collar 10 can increase its friction force for steel rope 6, this lifting machine can be prevented hook in time and drop in wire cable rupture, thereby avoids occurring article drop caused property damage and personal safety problem.
